I can't see them coming back. They're hemmed in. The further right they move, the less palatable they are to the majority of Australians. They can't go left without alienating their base.

They also don't have a leader to drag them kicking and screaming through the necessary process to change. Nor do they have the ability to recruit one young enough to make it worthwhile. It will be a long and painful exercise.

Right now, I fully expect them to continue along their rightward path. As a result, I can see them reduced to One Nation numbers within a couple of electoral cycles, which is still more than the Nats get. At some point, they'll likely splinter.
